The 2015 Honda Accord offered two gasoline engines and a hybrid option: a 2.4-liter inline-4 and a 3.5-liter V6, plus a Hybrid variant that uses a 2.0-liter engine paired with electric motors.
In practice, the 2.4L i-VTEC was the standard powerplant for most trims, typically paired with a continuously variable transmission (CVT), while the 3.5L V6 was reserved for higher trims and paired with a conventional automatic. The Accord Hybrid combines the 2.0L engine with electric motors and uses an electric CVT to blend power, delivering competitive efficiency without sacrificing smoothness.
Gasoline engine lineup
The following gasoline powertrains were available on the 2015 Accord.
- 2.4-liter inline-4 i-VTEC engine
- 3.5-liter V6 i-VTEC engine
These engines defined the performance and efficiency range for 2015 Accord models, with the 2.4L powering most trims and the V6 offering stronger acceleration in the upper tier.
Hybrid option
The 2015 Accord Hybrid uses a 2.0-liter i-VTEC Atkinson-cycle engine paired with electric motors and a battery pack to drive the car, with power delivered through Honda's electronic CVT system.
- 2.0-liter Atkinson-cycle inline-4 engine
- Electric motors and a lithium-ion battery; combined output around the mid-190s horsepower; uses an e-CVT
The hybrid delivers superior fuel economy and a quiet, smooth ride, though its acceleration characteristics differ from the V6 gasoline model.
Transmission and economy context
Powertrain mapping for the 2015 Accord varied by engine: the 2.4L gasoline engine typically paired with a CVT to optimize efficiency, while the 3.5L V6 used a 6-speed automatic. The Hybrid version uses an electric CVT to blend gas and electric drive seamlessly.
- 2.4L i-VTEC: CVT
- 3.5L V6: 6-speed automatic
- Hybrid: electric motors with e-CVT
All engines incorporate Honda's i-VTEC variable valve timing technology for a balance of performance and efficiency.
Summary
In short, the 2015 Honda Accord offered two gasoline engines—a 2.4-liter inline-4 and a 3.5-liter V6—and a Hybrid variant featuring a 2.0-liter engine with electric motors. Transmission choices varied by powertrain: CVT for the 2.4L, a 6-speed automatic for the V6, and an e-CVT for the Hybrid. This mix aimed to cater to both efficiency-minded buyers and those seeking stronger performance.
